Both phenomena have consequences at regional and local scales and influence the quality of air of the surrounding areas. CENIZA is a networking project (2010-2012)funded by the Ibero-American Development Programme for Science and Technology ( Red temática CYTED-410RT0392 http://www.bsc.es/case/projects/ceniza/) a Programme aimed at combining different perspectives and visions to promote cooperation in Research and Innovation for the development of the Latin America region. The CENIZA network gathers institutions from seven different Latin-American countries (Argentina, Chile, Colombia, Ecuador, Mexico, Nicaragua, and Spain) and is devoted to monitoring, modelling and forecasting volcanic ash and aerosol dispersion. Focussing on large urban areas located nearby active volcanoes, the network has developed and implemented the necessary tools for a daily forecast of ash fallout during eruptions and airborne gas/aerosol concentration from diffuse emissions. The modelling system can also be used to reproduce eruptions that have occurred in the past and for fallout hazard assessment. A second goal has been to investigate the role of volcanic emissions on local atmospheric pollution and its effects on air quality and human health at short and mid-term.
